3.445 x 4.125
10.52:1
4000 RPM, BUT I need to run on pump gas.
1.780 318 intake valves.
7.005" connecting rod length.
Needing to run on pump gas is more important than "where" the peak torque will be.
According to D.V., the "optimum" LSA for the 225 is 106, but I don't hold that as gospel, necessarily.
